It's pretty simple to use - just go to https://flawless.is and enter your homepage or landing page URL.
I'm using the urlbox API to get a screenshot of your page, then I utilize GPT-4V to analyze the screenshot, find potential usability and conversion issues, suggest fixes, and highlight the relevant areas in the screenshot (although the position is sometimes inaccurate).
Last week, I launched it on Hacker News (https://news.ycombinator.com/item?id=38207892), but I wasn't ready for the 20,000 visitors that came next... Unfortunately, GPT-4V has a rate limit of 100 events daily, so almost no one could use the service - EPIC FAIL.
To manage demand, I now priced the service at $1.99 (still less than a cup of coffee), which should keep the demand at bay, and also cover the costs of GPT-4V, the screenshot API, and hosting.
As a proof of concept, there are some demo audits on the homepage you can click and check out.
Please let me know your thoughts and suggestions on how to improve it!
